I'm really struggling with an article I'm trying to write for work. 
Matthew presented me with some data he wanted me to use in an article about what podcasts do for your brain. The data has no citation or explanation of how it was gathered. The information simply said, "there's a famous study where people had to listen to the 'I Have a Dream' speech and the study found that when people listened to it, they were more engaged and remembered more details when they listened to audio only, rather than watching and listening to a video."
Again, nothing to back this up. Were the participants in an MRI machine? Did they self-report afterwards? Who did the study, and when? 
I've been beating myself up trying to find a reputable, consistent study that proves audio is more memorable than video. Turns out, it's not true. They're stored in different kinds of memory in different ways.  Citations available upon request. It took me over a week to get this info because I'm using Duck Duck Go. 

Last night, I was so frustrated that I made this video. It's about eight and a half seconds long. Watch this, then close your eyes, and ask yourself: 
What did I hear? (and, if the question applies, how many?)
​​​​​​​What did I see?  (and, if the question applies, how many?) 

Your answer will help me figure out this effing article and stop obsessing about this section of the article. 
​​​​​​​Further details as events warrant.

My dog is farting up a storm. 

I heard four chimes of a large bell. I saw five stained glass windows. I also saw chairs and benches but didn't accurately count them.
Noted. Thank you.
I heard the bell toll four times. I saw pews and three windows and a bit of reflected sunlight.
Noted. Thank you.
